I have a 1980 Columbia Western Flyer... Sach's Engine (505 I beleive... not at home as I post this).
I drained the trans fluid, and resealed the cover on the trans housing (remembering to keep that little gap open... I don't understand why that's there), filled it with ATF Trans fluid (the book says Type A... Every powersports, car and motorcycle shop had no idea what type A meant, and the car shops said to use regular ATF)
It seemed to behave fine.... but when I got back home from a trip to the pool (4 miles out, hour and a half there, 4 miles back) there was a wee bit of smoke/steam from the Trans, and a dribble of fluid form the aforementioned gap... and the colour of the fluid dribbling out, and through the entire trans when I poured some out... was like chocolate milk.
Whats wrong with my moped? Please don't tell me I need an entire trans... If I do, Is 1977mopeds going to have them, or need I order form an online shop?
